About this tool

IconVault's YAML to JSON Converter converts in both directions: YAML to JSON with clean pretty-printed output, and JSON to YAML with natural indentation and block style. Switch modes with one click, paste your document, and convert instantly. Invalid input gets a plain-language error message instead of a crash, so you know exactly what to fix.

Converted output can be copied to the clipboard or downloaded as a `.json` or `.yaml` file. The YAML parser loads on demand to keep the page fast, and everything runs fully in your browser with nothing uploaded, which keeps private configs safe. It is free to try, with a limited number of free conversions before Pro is suggested.
